CORD ADJUSTERFOR ELECTRIC DROP-LIGHTS.

Specification of Letters Patent. I P t t M 1915 Application filed March 18, 1913, Serial No. 755,178. Renewed August 8, 1914. Serial No. 855,935.

To all whom it may concern:

Be it known that I, GEORGE E. THQRBERG, citizen of the United States, residing at Mandan, in the county of Morton and State of North Dakota, have invented certain new various different positions within the room;

A further object of the invention is to provide a cord adjuster for electric drop lights which is simple and inexpensive in its construction, which can be readily applied to or removed from the electric light cord without injury thereto,and which admits of the desired adjustment being easily and quickly made.

Vith these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view of a cord adjuster for electric drop lights which is constructed in accordance with the invention. Fig. 2 is a top plan view of one of the cord clips. Fig. 3 is a transverse sectional view through the same, and Fig. 4 is a longitudinal sectional View on the line 4-4 of Fig. 3. 7 7

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to the drawing, the numeral 1 designates the usual cord or wire for the electric drop light 2. These cords l are usually longer than is required for most positions of the drop light, the surplus length of the cord being usually taken up by knotting the same or winding it upon some form of a spool or drum. The present cord adjuster comprises a pair of spring clips 3 and V 4 which are adapted to be detachably applied to the cord l-at different points in the length thereof, the said clips being permanently connected by a flexible cord or tie member 5. so that the surplus portion of the cord 1 may be looped and permitted to hang loosely between the two spring clips, as

shown by Fig. '1. 7

Each of the spring clips 3 an'd4 is con-' grasping the clip when applying the same to an electric lightcord or removing it therefrom. The other spring clip 4 has a substantially U shaped cross section, as indicated by Fig. 3, is preferably somewhat longer than the clip 2, and is curved longitudinally so as to conform in a general man-' ner to the usual curvature of the electric light cord. The edges of the spring clip 4 are provided with the respective outwardly extending flanges 5 and 6, while the ends of the clip 4 are flared as indicated at 4*. These flaredends 4 are shown more clearly by Fig. 4. The longitudinal flange 6 is preferably-somewhat wider than the flange 5' and is returned at 6 one end of the said returned portion 6 of the flange being longitudinally slit to provide a tongue which is'bent upwardly to form a hook member 7.

The length of the electric light cord 1 is properly adjusted by looping the surplus portion thereof between the twospring clips 3 and 4. The drop light 2 may then either be permitted to hang freely from the ceiling in its natural position, or be swung over and held in some other portion of the room. For the latter purpose it is contemplated to employ retaining cords 8, the said cords being permanently connected to articles of furniture or to the walls or fixtures of the room and being provided with the rings 9 which are adapted to detachably engage the hook member of the spring clip 4. Any desired number of these retaining cords 8 may be provided in the room for holding the lamp in diflerent positions, and when it is desired to shift the lamp from one position to another position, it is merely necessary to detach the ring 9 of one of the retaining cords 8 from the hook member 7 and to apincluding a spring cord formed from a single sheet of spring matej ply the ring 9 of the other retaining cord 8 1 to the hook member 7 after the position of the lamp has been shifted. The retaining cords 8 are preferably formed of elastic, since where the cords are connected to arti-' cles of furniture, the accidental movement. of the article of furnituremight otherwise result in the snap of the cord and the breakage of the lamp.

Having thus described the invention, what I claim as new and desire to secure by Let-' ters Patent, is

i 1. Acord adjuster for electric drop lights includi'nga cord engaging member, an independent spring clip adapted to engage the cord, said spring clip being curved longitudinally to conform to the curvature of the electric light cord, a tie member permanently connecting the cord engaging member and the clip, and a retaining cord connected to the clip.

2. A cord adjuster forelectric drop lights including a cord engaging member, an independent :cord engaging spring clip formed from a single sheet of spring material, said spring clip having a substantially U shaped cross-section and being-longitudinally curved to conform to the curvature of the'electric light cord, a tie member permanently connecting the cord engaging member and the cjip, and a retaining cord connected to the 0 1p.

3. A. cord adjuster for electric drop lights including a cord engaging spring clip formed from sheet material and being substantially U shaped in cross-section, one of the edges of the .clip being provided with a longitudinal slit to provide a tongue which is bent to form ahook member, a'retaining cord, and means upon the retaining cord for detachably engaging thehook member.

a. A cord adjuster for electric drop lights engaging clip rial and having a v U shaped cross-section, the said spring clip being provided at the mouth thereof with longitudinally disposed side flanges and one of the side flanges being re turned and slit to provide a tongue which is bent to form a hook, and a retaining cord provided with means for detachably engaging the hook.

5. A cord adjuster for electric drop lights including a cord engaging spring clip.

the mouth of the clip and one ofthe side flanges being slit to provide a tongue which is bent toprovide a double-hook, a pair ofretaining cords and means upon the-two retaining cords forindependently engaging:

the before mentioned. double hook.

6. A cord adjuster for electric droplights including a spring clip adapted gtO engage the cord and provided with a doublehook.

member, a pair ,of retaining cords, and means upon the two retaining cords for independentlyengaging the before mentioned double hook.

7. A cord adjuster cluding a cord engaging spring clip formed froma single sheet of spring material, said spring clip having. a substantially U shaped cross section and being longitudinally curved to conform to the curvature of the cord, and suspending means cooperating with. the springclip to hold the same in position.

8. A cord adjuster for electric droplights including. a" cord engaging spring clip formed from sheet material and being substantially .U shaped in cross segtion,;one of the edges of the clipbeing provided with a longitudinal slit to provide a tongue which is bent to form a hook member.

9. A cord adjuster for electric drop lights including a cord engaging clip formedfrom a single sheet of springmaterial and having a U shaped crosssection, the said spring clip 7 -90 being provided "at the mouth thereof with longitudinally disposed side flanges, and onev of the said flanges beingreturned and slit to provide a tongue which is bent to form a hook.

10. A cord adjuster for electric drop lights including a cord engaging clip having a.

substantially .U shaped cross section and be ing longitudinally curved to conform to the. curvature of the cord,: the month of:the=

spring clip being formed with a side flange,

and a hook member projecting from the side'- In testimony whereof I afliX my signature in presence of two witnesses.
